I was told by a few engine builders that you can take two different sized main bearing shells and combine them to get your desired clearance, I've done this and it has worked for me in the past. So this shouldn't be done?
Can you ahow what it looks like after a shop preps a head surface with a 3m roloc disk? What does the surface finish measure? High and low spots. Etc. I'm at a dealership and we use the blue 3m rotor disks for nearly every head and block surface. Would love to see that same surface 3m resurfaced, then machined.
@@revell7156: Don't do it, especially on aluminum heads! Using a 3M Roloc for anything but the slightest of clean-up makes for a short trip to the next blown head gasket. Shops which do this are, generally, low-budget, schlock operations. You can bet that the customer gets charged just as much as if the head(s) were sent to a good shop and surfaced correctly.

A friend of mine, who was a pro motorcycle mechanic (working for som of the top racing teams in Europe back in the 90s) was rebuiding a GSXR 1000 one night, I was there watching, so was the owner. This guy never rushes anything, the work is slow but top notch. The owner got stressed and tried to rush my friend to work faster. When he took a pencil and eraced Suzukis nubers on the main bearings, the owner really rolled his eyes; Why not just mount them, right out of the box? When he unpacked bearing nr 3, he found that Suzuki had packed two different size bearing halves in the same box.. Saved the owner from a very expensive experience.. I wil never forget that..
That's exactly why a good shop doesn't allow customers in the shop. I used to hear people "well, they don't want you in the shop because they're trying to hide something!" That might be true in some instances, but mostly, it's a matter of liability and having to comply with insurance requirements - when I left the automotive repair industry in 2002, shops had to have $1,000,000.00 worth of liability insurance in case a customer got hurt on the premises. Gas stations that also did repairs were worse. They had to carry a million for the shop, and a million for the rest of the station. And, as the story illustrates, it's a matter of distracting the guy that's performing an expensive repair on your vehicle, and potentially costing you a lot more because you wanted to hang around.
Always enjoy your videos. It would be great to have follow up footage on the engines [when possible] to see the engine running in the vehicle, and customer comments on finished product. An epilogue as it were.
As a teen I worked in a tractor dealership. Every time we had an engine that needed machine work I spent the better part of my days at the machine shop watching the work being done. Crank Grinding, cylinder boring, head/valve work done, etc. The guys in the shop appreciated my interest and taught me a lot over those years. This reminds me of those years very much.

I live nearly 2000 km (1250 mi.) away in Northern Alberta Canada. I watch all your videos. I wish it was plausible to ship you the motor out of my 1974 674 International for rebuild.

When you were talking about cylinder clearance it brought back memories of my old 74 Chevy truck, it had a 250 straight six and 3 on the tree in 1998 I paid $400 for it. During the winter of 99 on a Saturday I had to work the morning was freezing cold but when I got off at 1 o'clock it was 60 degrees, it never occurred to me that I had a piece of cardboard in front of the radiator until the temp light came on, seconds later the engine developed a misfire. I stopped and removed the cardboard and drove home. Number 6 cylinder had no compression. I pulled the head and found the number 6 piston cracked around the ring land, it got tight and popped it. Spent the rest of the night getting the piston out. On Sunday I ordered a piston and rings and gaskets from Napa and left my piston and rod with them so they could press the new piston on the rod, the machine shop guy wasn't there on Sundays and I didn't have any spare cash to offer as an incentive. Monday I had to get a ride to and from work. When I got home I measured the bore, without honing for a crosshatch I had .007" clearance, after honing I had just over .008", the taper was about the same. I had Napa mic the piston because all I had was an inside mic set that I inherited from my dad and a 1"-2" outside micrometer so I knew my inside mic was accurate at 1" and 2", I figured it would be good at whatever the bore was. I reassembled her and she purred like a kitten again. No smoke either. She served me well for a few more years but sadly the power train was still in great shape when the body rot ended her life. And it still used a points ignition. The job wasn't daunting at all, no different than doing an in-frame on a diesel. I think the whole job cost me $60 in parts and I already had the tools. I'm still amazed at the results I got with the cylinder wear it had, I was sure she was going to be a smoker.
Back in my day we would knurl piston skirts and valve guides to tighten things up when clearances were loose but owners had no money to proper repairs. Nicholas probably would laugh out loud at the thought but I wonder if the Cleaning Guy ever did that stuff?
At our old we always tried to help out the regular guys. We didn't waste all that time measuring the fly crap. Taking hours to deglaze cylinders. We got $8 a cylinder to deglaze with either 3 stone or ball hone. If you're not going to bore it, why should I charge the customer $90 an hour for all that fussing. We did what the customer could afford. Did it 50 yrs never had a come back. Always instructed customer on assembly.
CONGRATULATIONS. Having your first baby is going to be a wonderful time. I have 1 daughter and 3 granddaughters and I wouldn’t change anything. So much fun.
Chevrolet and GMC may have made one million of these engines. I had no idea of the complex measurements and procedures required to bring one back into proper operation. This is a fine video. Thanks, Gentlemen!
For an old gear head who was in another field of work, it's very interesting to see all your various machines in set up and operation, greatly enjoy your channel and respect your work.
OMG Gentlemen, what a masterclass. I love the way you "out loud" your thought processes, thinking, and understanding of the challenge. It's so informative, educational and instructive. Your experience, skill and understanding of your trade is obvious I'm addicted to this channel now, which just isn't FAIR 😂😂 NEW SUBSCRIBER from Ireland 🇮🇪 👏👏 thank you both so much God Bless
This engine brings back memories for me I was assembling a 454 Chevy engine for my uncles motorhome and when I checked the bearing clearances all were good except one ...as it turned out there was standard bearings in an under size box ...the parts guy at the engine shop that did the machine work could not believe that I found this problem because he said no one checks all the bearings...I said I do ..I was taught to be thorough ...thanks for sharing your good work with us
Hi I'm from South Africa in a little Town called Pietermarizburg and I was an Automotive machinist about 20 years ago when I broke my back in 3 places and are unable to work or drive.... So when watching these pod cast with Critical thinking and truthful content brings back the good year's I spent in the workshop .......... Thank you guy's once again for brilliant pod casts that bring back awesome memories that I miss terribly........👏👏👏👏.............
I love this show. I'll watch it through the night. I spent time learning with my Dad many moons ago. My Dad restored Old VW Bugs....I sure do miss those days.
I just recently found your channel and I do enjoy watching it. I started working as a mechanic for my Father in 1964 and worked on automobiles until I moved to Alaska in 1986 and worked mostly on heavy equipment. I also got my welding certifications that almost guarantees you a job in Alaska. Over the years I received a degree in electronics and retired from that field in 2005 I have been retired since 2005 and the last 235 I worked on was probably in the late 1970's so it has been 40 years since I had the head off of one, but if my memory is correct, the 235 was a full pressure oil system and used bearing inserts. I have never seen an engine that used inserts and shims. The shims were used on the earlier 216 with babbit bearings. The method you described to adjust them is what I remember as well, but I don't remember ever seeing a 235 with babbit bearings. We checked the clearance with plasti-gauge on every rod and main bearing on every overhaul, .002 to .003 was acceptable, any more they would burn oil because of the excess getting thrown toward the top end. There were oversize bearings then, .003, .004, and .005, but my Father would not use them. It was time to turn the shaft or put in a short block. We also did not put lubricant on the bearings when we installed them. My Father felt it was an easy way to get dirt under the cap without knowing it. We removed an oil galley plug and attached a hose from a portable oil pump and lubed the engine just before we started it. Great channel, it brings back a lot of memories. . . .
You guys make an awesome team ! My Grandfather taught me a bunch. He had a huge factory and he was the master of the tool and die room ! 3 Bridgeports and a lathe ! I'll never forget his Gerstner wooden toolbox !
From a guy who taught himself engines and machining your videos are spot on. Very much enjoyed this and looking forward to more on this engine. Great job guys.
Jims shop gives us pistons heads comfort.. This is our happy place. Many don't understand, but this methodical craftsmanship, is what keeps us going around the world... and a way to pay for those babies... Ha
Not very many years before poured Babbitt bearings were the industy " norm ". So this motor is a pioneer with insert bearings. Lots of finess to fit properly. Great video. This motor will run many years.
Many people expect, ( Fast, Cheap, and Perfect. ) Rushing a task usually creates problems, Cheap labor usually gets low quality, and Perfection isn't realistic when combined with the first two. I love watching your videos. I admire your value of doing your best. Both of you guys should be very proud.
I sure miss machining. I didn't spend too much time in automotive, about 6 years back in the 70's, and mostly on my own stuff, including a 235 chevy. But I spent another 47 years in high tech molding and associated tooling as well as R&D. The last decade or so was mixed with engineering and CAD/CAM integration, which I fought tooth and nail, to no avail. Disability of some sort comes to us all and all this is just a memory for me now. Thanks for giving me a few moments like I was back there in my good old days.
Returned to watch these videos that I missed before and I want to thank you for making these! Your father and son relationship resonates the same vibes that me and my dad have. When he still was in better condition, we assembled one B20 motor that was machined in local machineshop and I will always remember that. It was a fresh engine for my Volvo 142 -72 that I used to drive when got my drivers licence ❤ So many good memories, nowadays I work as a machinist for local production machinery where we do a lot of different parts for the industry and I love it 😊 Love all the different machining work that you post and its always a good time to spend watching, much love from Finland ❤
I pulled a abandon 65 Chev 1/2 side step out of a potato field that had three broken piston and brought it back to life . By replacing all piston and connecting rods that came out of a 283 .. ran like a champ ..the engine out lasted the body of the truck .
Did a 440 Mopar once that the crank wouldn't turn at the final torque spec which I believe was 105. It would spin free at 100. The block came from a local machine shop to replace a cracked one. Turns out they were missing a main cap and used one of our originals without align honing or even telling us. I was amazed that just a few pounds of torque made such a huge difference.
I hope you drill the block to give full pressure rather than bypass oil filtering. Simple change by machine shop. I am an odd ball as I love the 235 - have two city under bench and obviously one in my 54 3100
In the first video of this series where you initially discovered the 20 bearing, the cap was originally bolted on with the nipple towards the 3rd bearing. You've turned it around on re-assembly so the nipple was towards the 1st bearing. Maybe having the cap bolted the wrong way round was the reason the 20 bearing was in there in there from the last workshop.
There's a few channels on youtube that I really enjoy, but the father and son ones seem the best, in my opinion. Love you guys, thank God your fathers passing along his knowledge. Lord knows we've lost a lot of it in the last 40 to 50 years.
your videos always brings back memories . I have used the old style boring bar that bolted to the block. But i don' remember working on any old stovebolt 6s. They were gone and smallblocks were swapped in.
The care you put into work like this is far beyond what most people would do and far better than what was available back then. That engine will be better than new.
Always a pleasure to watch and hear a master of their trade at work. The old 235 Chevy engine did not put out a lot of horses but it was a dependable engine in its day as was the 265 V8 and 283 that followed.
Have this engine in 1967 C-30 dumptruck with heavy gravel box. The origal engine was swapped for the smaller displacement earlier engine. Must be a good engine.
You were talking about that old van Norman boring bar. Me and dad used that on alot of engines that we overhauled at the farm. I believe my grandfather bought it. It didn't run on 110 volts either. We had a setup with an 110 electric motor driving the generator that supplied the correct voltage which I don't remember what that was. Why the different voltage I don't know. But it worked great.
In UK we use a 240 to 110 step down transformer. I’ve never done it, but connected the other way around should give a voltage step up. The only use for a motor-generator that I know is where the mains power single phase and the load is three phase.
Howdy from Sacramento! Your dad is so cool, and I like how there is mutual respect between you. You're blessed to be able to work together. Thanks for sharing!
Funny our boss used to mix up the main caps in rod caps, to test us to see how fast we can match them up. He taught us how to match up the machine marks.
Hi guys I wish more people from all walks of life would take this kind of care and pride in their work , no matter what they’re doing please just do it right , there is no substitute for experience and knowledge, Regards Davy 🏴🇹🇭
Really like your channel like the interaction between you two. Very respectful. Would love to see you guys do a full rebuild on a 351 Cleveland q code. 4 bolt mains. I’m gonna be rebuilding one and I’m no mechanic. Will need all the help I can get lol. Keep the videos comming really enjoyable
For engines like this 235 where it's hard to get (or not hard to get) oversize pistons the Line2Line coating worth looking into to tighten up the piston to wall clearance.
Excellence personified,,,, keep it up ❤❤ you work on a level I completely understand I came from a machine shop/toolroom where everything HAD to be right. Nobody checked my work,,,, it went out the door and never came back.
torque plates are only necessary when your building race engines. most engine shops don't use them unless the customer insists on it. also, that is the cleanest honing lube I have ever seen.
Love watching you guys. I'd be that old guy that said "we did hundreds of those old Chevys". Measure the bores, ball hone it 15 seconds a cylinder, send it down the road. Actually measuring the finish? Are you serious? Why do they make ball hones? Why do they make plateau hones? Used them for years in our shop. Never had an issue. My old boss would have given us hell for all that diddling around. Your not boring it, measure and reglaze it, get it done!
I love all the information you guys share, I used to work at a machine shop when I was just out of high school, I was the cleaning guy 😂😂. And Nick, congratulations to you and your family! I send my best wishes to you and the Mrs. I bet the cleaning guy is excited to meet his grand baby!
Those big openings where the deck is not fully down is due to those being water jackets and the water etching the surface there so tahts why its really eaten up in those spots. Since the Gaskets are used for multiple applications and heads too so some times water jackets and such dont expose or need to be there. But those areas where there is bad eatin up from the water jackets being dead end there, I've seen some blocks where they ate a giant divit into the surface LOL. That deck is PERFECT!!!! You guys rock!
Ive done some of the shimed motors, rods and mains but they were poured babbit brgs,,, i do remember they recommended to get your correct tolerances , the shims were to be added or subtracted from the cam shaft side of the block. Im really enjoying this particular series, nice job guys!
Your videos are a pleasure to watch, ole dogs can still learn new tricks. Thanks for being so thorough in your explanation of the process and cure of issues, looking forward to the next one, only wish you had a dyno, I'd love to see this run.
Watching this assembly brought back some memories of similar situations. Went to a local engine rebuider outside of Garland Tx around 70. He had worked for Mustang Rebuilders in Garland for years... Anyway he had a 230 he was rebuilding. He set bearing halfs in block the caps. Lub them, set crank in place torqued caps...then picked up a heavy balling hammer. As he turned crank beginning with rear main cap he messaged main caps till crank turned smoothly. I ask him, WHAT WAS HE DOING? ANWSER: Line boring block! Never went back!!
@3:20 I bought that same dial indicator set at Burtonsville Speed and Sport in the early 80s to do my first cam degreeing job on the 327/300 I built for my 70 Camaro. Pretty cool seeing it the cleaning guy use it!
Doing these Chevy blocks are a trick I always ream the main cap bolt holes if you don't it will tear the sides of the bearings as most builders use plastic gauge .you produce great shows Hello from Australia Cheers wayne
I haven't been in a machine shop but this was so enjoyable to just sit down and drive in BeamNG with. Car guys talking about car stuff while I drive cars in a game? Bliss Keep up the great work gentlemen!
I love watching machining videos that being said I've heard some say that when " decking " or surfacing something to make it perfectly flat you can sometimes induce stresses in the material to the point when you unclamp the piece it will no longer be perfectly flat due to said stresses, when you deck the head and block is it the fact that your only removing a minute amount and the shear mass of the piece that you don't have to worry about that ???? now I believe when that has been mentioned the material would be like decking flat stock IDK just a question that popped into mind 😁
I know that happens to comparably new blocks because they are not relaxed through heat cycles, older blocks especially cast iron shouldn't do this. That might be wrong but it's what I have been told
@@Dave5843-d9m that has nothing to do with what the block dose while unclamping after milling, the dye coat if showing you what your starting with. The bulging I would guess is caused by over torquing the bolt pulling the thread material outward :( Thanks for replying to my comment :)
I can watch these videos all day, despite the fact I understand almost nothing of what you are saying. Handicraft skill and applied experience are always fascinating. Maybe I even learn something along the way!
In the few motors I have rebuilt over the years I've come across miss matched bearings, beveled bearings that didnt have a bevel and even bearings missing from the sealed package. I'm very happy when I get past the bearing stage of building a motor.
first off congratulations on the baby girl can't wait to see all 3 of you machining blocks and tractors. also thanks for all the great videos as a craftsman myself (union carpenter) it's refreshing seeing another craftsman really show there craft and knowledge. btw i have a quick question, how much can you surface a block (especially older blocks) before you can't or is there ways to fix a block if you have to machine past "the point of no return"
Great job, i think you are machining that engine better than new. They used these 235 blueflame engines in lobster boats in newengland, they were real work horses. I rebuilt one in the late 60s and the owner never touched it for twenty years except for changing oil.not even adjusting the valves. Its getting harder to find machine shops like yours. Keep on working. Thanks
I presume they get larger in diameter towards the rear, yes? The front main is supporting the crankshaft front bearing, the second, on this engine is supporting a bearing that is taking the load of two cylinders, the third takes four and the final crank bearing is taking the power of all six cylinders and holding a flywheel. An old truck or car engine never drives much off the front of the engine like a tractor with a front power take-off, so it kind of makes sense.
Thanks for the great content in your videos. Much more informative than TV, really makes me appreciate the quality of your work and the effort you put into editing the videos and explaining important details. I had a 52 Chevy with a 235 , really a sweet little engine.
I'm just glad I don't have to deal with those ancient artifacts. 🙏😬 However, I do enjoy all the fire hoops and spiked bottom pits you have jump thru to get everything squared and properly configured. Stay classy, JAMSI ! 👌

And it still used a points ignition.
The job wasn't daunting at all, no different than doing an in-frame on a diesel. I think the whole job cost me $60 in parts and I already had the tools.
I'm still amazed at the results I got with the cylinder wear it had, I was sure she was going to be a smoker.
Back in my day we would knurl piston skirts and valve guides to tighten things up when clearances were loose but owners had no money to proper repairs. Nicholas probably would laugh out loud at the thought but I wonder if the Cleaning Guy ever did that stuff?
At our old we always tried to help out the regular guys. We didn't waste all that time measuring the fly crap. Taking hours to deglaze cylinders. We got $8 a cylinder to deglaze with either 3 stone or ball hone. If you're not going to bore it, why should I charge the customer $90 an hour for all that fussing. We did what the customer could afford. Did it 50 yrs never had a come back. Always instructed customer on assembly.

CONGRATULATIONS. Having your first baby is going to be a wonderful time. I have 1 daughter and 3 granddaughters and I wouldn’t change anything. So much fun.
I feel blessed when we get TWO videos in ONE week!! Thanks, guys, for showing the world the correct way to do automotive machine work.
Chevrolet and GMC may have made one million of these engines. I had no idea of the complex measurements and procedures required to bring one back into proper operation. This is a fine video. Thanks, Gentlemen!
For an old gear head who was in another field of work, it's very interesting to see all your various machines in set up and operation, greatly enjoy your channel and respect your work.
As an owner of several Chevy inline 6s over time, I found this series very interesting. Thanks!
yeah.. i'm solely here for the blue flame stove bolt
I loved working on those inline 6's. I had 5 chevy cars with that engine. Had a boat with 2 6's. Easy to work on in a bilge compared to a V8.
OMG Gentlemen, what a masterclass. I love the way you "out loud" your thought processes, thinking, and understanding of the challenge. It's so informative, educational and instructive.
Your experience, skill and understanding of your trade is obvious
I'm addicted to this channel now, which just isn't FAIR 😂😂
NEW SUBSCRIBER from Ireland 🇮🇪
👏👏
thank you both so much
God Bless
This engine brings back memories for me I was assembling a 454 Chevy engine for my uncles motorhome and when I checked the bearing clearances all were good except one ...as it turned out there was standard bearings in an under size box ...the parts guy at the engine shop that did the machine work could not believe that I found this problem because he said no one checks all the bearings...I said I do ..I was taught to be thorough ...thanks for sharing your good work with us
I always check all bearings. I have a great machinest, still I check all his work just to be on the safe side.
I really enjoy these longer videos!!! More time to listen to the cleaning guy explain the meaning of life!
Man your dad is a legend! Cherish every single moment you guys spend working together. This engine is going to run amazing!
So glad I found this channel. I’m fascinated with this as a 43 year old bloke from England.
Extremely interesting ! You guys are spending a lot of time on this restoration ! Setting up the Mains is a eye opener for me ! Thanks for sharing !
"Near enough is not good enough.
Perfect is good enough"
Well thought through guys, a pleasure watching.
Hi I'm from South Africa in a little Town called Pietermarizburg and I was an Automotive machinist about 20 years ago when I broke my back in 3 places and are unable to work or drive.... So when watching these pod cast with Critical thinking and truthful content brings back the good year's I spent in the workshop .......... Thank you guy's once again for brilliant pod casts that bring back awesome memories that I miss terribly........👏👏👏👏.............
I love this show. I'll watch it through the night. I spent time learning with my Dad many moons ago. My Dad restored Old VW Bugs....I sure do miss those days.
I just recently found your channel and I do enjoy watching it. I started working as a mechanic for my Father in 1964 and worked on automobiles until I moved to Alaska in 1986 and worked mostly on heavy equipment. I also got my welding certifications that almost guarantees you a job in Alaska. Over the years I received a degree in electronics and retired from that field in 2005
I have been retired since 2005 and the last 235 I worked on was probably in the late 1970's so it has been 40 years since I had the head off of one, but if my memory is correct, the 235 was a full pressure oil system and used bearing inserts. I have never seen an engine that used inserts and shims. The shims were used on the earlier 216 with babbit bearings. The method you described to adjust them is what I remember as well, but I don't remember ever seeing a 235 with babbit bearings. We checked the clearance with plasti-gauge on every rod and main bearing on every overhaul, .002 to .003 was acceptable, any more they would burn oil because of the excess getting thrown toward the top end. There were oversize bearings then, .003, .004, and .005, but my Father would not use them. It was time to turn the shaft or put in a short block.
We also did not put lubricant on the bearings when we installed them. My Father felt it was an easy way to get dirt under the cap without knowing it. We removed an oil galley plug and attached a hose from a portable oil pump and lubed the engine just before we started it.
Great channel, it brings back a lot of memories. . . .
I really enjoy your videos. I really appreciate the expertise and the wholesome relationship between father and son.
You guys make an awesome team ! My Grandfather taught me a bunch. He had a huge factory and he was the master of the tool and die room ! 3 Bridgeports and a lathe ! I'll never forget his Gerstner wooden toolbox !
From a guy who taught himself engines and machining your videos are spot on. Very much enjoyed this and looking forward to more on this engine. Great job guys.
Love watching you interact with your old man, you're truly blessed my man...
Jims shop gives us pistons heads comfort.. This is our happy place. Many don't understand, but this methodical craftsmanship, is what keeps us going around the world... and a way to pay for those babies... Ha
That new honing oil looks good. All I remember was the black stuff. Thanks for the videos. I love watching precision machining.
Not very many years before poured Babbitt bearings were the industy " norm ". So this motor is a pioneer with insert bearings. Lots of finess to fit properly. Great video. This motor will run many years.
Many people expect, ( Fast, Cheap, and Perfect. ) Rushing a task usually creates problems, Cheap labor usually gets low quality, and Perfection isn't realistic when combined with the first two.
I love watching your videos. I admire your value of doing your best. Both of you guys should be very proud.
I could watch you guys all day long, the experience and knowledge you guys have is awesome 👍🇺🇸🇺🇸
I sure miss machining. I didn't spend too much time in automotive, about 6 years back in the 70's, and mostly on my own stuff, including a 235 chevy. But I spent another 47 years in high tech molding and associated tooling as well as R&D. The last decade or so was mixed with engineering and CAD/CAM integration, which I fought tooth and nail, to no avail. Disability of some sort comes to us all and all this is just a memory for me now. Thanks for giving me a few moments like I was back there in my good old days.
I know nothing about what you are doing but I love watching your channel. I love you guys.
Returned to watch these videos that I missed before and I want to thank you for making these! Your father and son relationship resonates the same vibes that me and my dad have. When he still was in better condition, we assembled one B20 motor that was machined in local machineshop and I will always remember that. It was a fresh engine for my Volvo 142 -72 that I used to drive when got my drivers licence ❤ So many good memories, nowadays I work as a machinist for local production machinery where we do a lot of different parts for the industry and I love it 😊 Love all the different machining work that you post and its always a good time to spend watching, much love from Finland ❤
You are so lucky to work in such a wonderful environment, I am thankful that you share your talents with us!
Wish I had a dad like the cleaning guy. He's a good guy.
I pulled a abandon 65 Chev 1/2 side step out of a potato field that had three broken piston and brought it back to life . By replacing all piston and connecting rods that came out of a 283 .. ran like a champ ..the engine out lasted the body of the truck .
Did a 440 Mopar once that the crank wouldn't turn at the final torque spec which I believe was 105. It would spin free at 100. The block came from a local machine shop to replace a cracked one. Turns out they were missing a main cap and used one of our originals without align honing or even telling us. I was amazed that just a few pounds of torque made such a huge difference.
I hope you drill the block to give full pressure rather than bypass oil filtering. Simple change by machine shop. I am an odd ball as I love the 235 - have two city under bench and obviously one in my 54 3100
Still run 1 also in my 59 1/2 ton Apache ..original 235
In the first video of this series where you initially discovered the 20 bearing, the cap was originally bolted on with the nipple towards the 3rd bearing. You've turned it around on re-assembly so the nipple was towards the 1st bearing. Maybe having the cap bolted the wrong way round was the reason the 20 bearing was in there in there from the last workshop.
There's a few channels on youtube that I really enjoy, but the father and son ones seem the best, in my opinion. Love you guys, thank God your fathers passing along his knowledge. Lord knows we've lost a lot of it in the last 40 to 50 years.
You might be on to something, another one of my favorite channels is Stud Pack it’s a father son carpentry channel.
A father and son getting along is a nice wholesome experience.
As a guy who also occasionally edits hour long videos, thanks for doing it. I love the long content.
your videos always brings back memories . I have used the old style boring bar that bolted to the block. But i don' remember working on any old stovebolt 6s. They were gone and smallblocks were swapped in.
The care you put into work like this is far beyond what most people would do and far better than what was available back then. That engine will be better than new.
Congrats man!! Get ready to have your whole world change when the baby comes!
I loved one of the final comments, "when it came in here it had already gone 10 miles more than this one". Humility.
Always a pleasure to watch and hear a master of their trade at work. The old 235 Chevy engine did not put out a lot of horses but it was a dependable engine in its day as was the 265 V8 and 283 that followed.
Have this engine in 1967 C-30 dumptruck with heavy gravel box. The origal engine was swapped for the smaller displacement earlier engine.
Must be a good engine.
You were talking about that old van Norman boring bar. Me and dad used that on alot of engines that we overhauled at the farm. I believe my grandfather bought it. It didn't run on 110 volts either. We had a setup with an 110 electric motor driving the generator that supplied the correct voltage which I don't remember what that was. Why the different voltage I don't know. But it worked great.
In UK we use a 240 to 110 step down transformer. I’ve never done it, but connected the other way around should give a voltage step up.
The only use for a motor-generator that I know is where the mains power single phase and the load is three phase.
Howdy from Sacramento! Your dad is so cool, and I like how there is mutual respect between you. You're blessed to be able to work together. Thanks for sharing!
Funny our boss used to mix up the main caps in rod caps, to test us to see how fast we can match them up. He taught us how to match up the machine marks.
the best duo and channel on all platforms . absolutely love watching your craft
I love watching you guys. A good machinist is like gold, and you gentlemen shine!
Those venerable dial gauges would benefit from new clear glasses. I’m sure a clock maker could help.
They sell replacement super cheap. Easy to install. No clock maker necessary
I still bore blocks with my old Van Norman 777 , I had it for 40 years !
Hi guys
I wish more people from all walks of life would take this kind of care and pride in their work , no matter what they’re doing please just do it right , there is no substitute for experience and knowledge,
Regards Davy 🏴🇹🇭
I am enjoying watching your videos. I’ve dropped blocks & heads off at a machine shop but never seen the process
Really like your channel like the interaction between you two. Very respectful. Would love to see you guys do a full rebuild on a 351 Cleveland q code. 4 bolt mains. I’m gonna be rebuilding one and I’m no mechanic. Will need all the help I can get lol. Keep the videos comming really enjoyable
For engines like this 235 where it's hard to get (or not hard to get) oversize pistons the Line2Line coating worth looking into to tighten up the piston to wall clearance.
It was pretty neat to see the decking progress .002 at a time.
Excellence personified,,,, keep it up ❤❤ you work on a level I completely understand I came from a machine shop/toolroom where everything HAD to be right. Nobody checked my work,,,, it went out the door and never came back.
torque plates are only necessary when your building race engines. most engine shops don't use them unless the customer insists on it. also, that is the cleanest honing lube I have ever seen.
Thanks for digging in to this
Love watching you guys. I'd be that old guy that said "we did hundreds of those old Chevys". Measure the bores, ball hone it 15 seconds a cylinder, send it down the road.
Actually measuring the finish? Are you serious?
Why do they make ball hones? Why do they make plateau hones?
Used them for years in our shop. Never had an issue. My old boss would have given us hell for all that diddling around. Your not boring it, measure and reglaze it, get it done!
I love all the information you guys share, I used to work at a machine shop when I was just out of high school, I was the cleaning guy 😂😂. And Nick, congratulations to you and your family! I send my best wishes to you and the Mrs. I bet the cleaning guy is excited to meet his grand baby!
Those big openings where the deck is not fully down is due to those being water jackets and the water etching the surface there so tahts why its really eaten up in those spots. Since the Gaskets are used for multiple applications and heads too so some times water jackets and such dont expose or need to be there. But those areas where there is bad eatin up from the water jackets being dead end there, I've seen some blocks where they ate a giant divit into the surface LOL. That deck is PERFECT!!!! You guys rock!
Machinist rule; before we change size/dimensions we check part numbers to make sure we have the right parts. 😊
Ive done some of the shimed motors, rods and mains but they were poured babbit brgs,,, i do remember they recommended to get your correct tolerances , the shims were to be added or subtracted from the cam shaft side of the block. Im really enjoying this particular series, nice job guys!
Thanks for the cool idea for a 'multiple tread lifting eye'. Gonna make a couple this weekend. Thanks for the great content!
Your videos are a pleasure to watch, ole dogs can still learn new tricks. Thanks for being so thorough in your explanation of the process and cure of issues, looking forward to the next one, only wish you had a dyno, I'd love to see this run.
Watching this assembly brought back some memories of similar situations. Went to a local engine rebuider outside of Garland Tx around 70. He had worked for Mustang Rebuilders in Garland for years...
Anyway he had a 230 he was rebuilding. He set bearing halfs in block the caps. Lub them, set crank in place torqued caps...then picked up a heavy balling hammer. As he turned crank beginning with rear main cap he messaged main caps till crank turned smoothly.
I ask him, WHAT WAS HE DOING?
ANWSER: Line boring block!
Never went back!!
“ Something is not quite right with that cap. We will never know. All I know is we have to deal with what we have right now.” Mark of a true expert!
This is high quality watching and even higher quality machining! Thank you!
Also congratulations on parenthood!
@3:20 I bought that same dial indicator set at Burtonsville Speed and Sport in the early 80s to do my first cam degreeing job on the 327/300 I built for my 70 Camaro. Pretty cool seeing it the cleaning guy use it!
Doing these Chevy blocks are a trick I always ream the main cap bolt holes if you don't it will tear the sides of the bearings as most builders use plastic gauge .you produce great shows
Hello from Australia Cheers wayne
I haven't been in a machine shop but this was so enjoyable to just sit down and drive in BeamNG with. Car guys talking about car stuff while I drive cars in a game? Bliss
Keep up the great work gentlemen!
I love watching machining videos that being said I've heard some say that when " decking " or surfacing something to make it perfectly flat you can sometimes induce stresses in the material to the point when you unclamp the piece it will no longer be perfectly flat due to said stresses, when you deck the head and block is it the fact that your only removing a minute amount and the shear mass of the piece that you don't have to worry about that ???? now I believe when that has been mentioned the material would be like decking flat stock IDK just a question that popped into mind 😁
You might have noticed the very first cut with blue dye showed “bulging” around the first head bolt hole.
I know that happens to comparably new blocks because they are not relaxed through heat cycles, older blocks especially cast iron shouldn't do this. That might be wrong but it's what I have been told
@@Dave5843-d9m that has nothing to do with what the block dose while unclamping after milling, the dye coat if showing you what your starting with. The bulging I would guess is caused by over torquing the bolt pulling the thread material outward :( Thanks for replying to my comment :)
I can watch these videos all day, despite the fact I understand almost nothing of what you are saying. Handicraft skill and applied experience are always fascinating. Maybe I even learn something along the way!
I never expected another hour long video so soon after the last one. 👍
In the few motors I have rebuilt over the years I've come across miss matched bearings, beveled bearings that didnt have a bevel and even bearings missing from the sealed package. I'm very happy when I get past the bearing stage of building a motor.
Mmmm, you got a New 8 stone/diamond honing head....Great stuff..
first off congratulations on the baby girl can't wait to see all 3 of you machining blocks and tractors. also thanks for all the great videos as a craftsman myself (union carpenter) it's refreshing seeing another craftsman really show there craft and knowledge.
btw i have a quick question, how much can you surface a block (especially older blocks) before you can't or is there ways to fix a block if you have to machine past "the point of no return"
Great job, i think you are machining that engine better than new. They used these 235 blueflame engines in lobster boats in newengland, they were real work horses. I rebuilt one in the late 60s and the owner never touched it for twenty years except for changing oil.not even adjusting the valves. Its getting harder to find machine shops like yours. Keep on working. Thanks
I've rebuilt a few of these 235/261's and never could understand GM's theory with the stepped main bores.
There was no theory ,their machinery was 50 years old and they were too cheap to replace it or buy new . I am a 39 year GM retiree machinist.
I presume they get larger in diameter towards the rear, yes? The front main is supporting the crankshaft front bearing, the second, on this engine is supporting a bearing that is taking the load of two cylinders, the third takes four and the final crank bearing is taking the power of all six cylinders and holding a flywheel. An old truck or car engine never drives much off the front of the engine like a tractor with a front power take-off, so it kind of makes sense.
Thanks for the great content in your videos. Much more informative than TV, really makes me appreciate the quality of your work and the effort you put into editing the videos and explaining important details. I had a 52 Chevy with a 235 , really a sweet little engine.
Awesome gentlemen. A real pleasure to learn from watching your work.
Very much enjoying the calm, deliberative expertise.
All these beautiful machines! It would be a HUGE investment today for someone starting a machine shop like that anew.
Congratulations!! We wanna see all baby pics soon.... wishing you all joy and happiness...
❤
I'm just glad I don't have to deal with those ancient artifacts. 🙏😬
However, I do enjoy all the fire hoops and spiked bottom pits you have jump thru to get everything squared and properly configured.
Stay classy, JAMSI ! 👌
It's so cool to see the thought process from such an experienced man and to see him pass that on to his son and to us.
Thanks for sharing y'all's talents and adventures!!!
Treating the old stovebolt too good. Diamond honed with surface specs. Noice! 😅
